Application filed June 15, 1916. Serial No. 103,798.

To all whom it may concern:

Be it known that I, JANE WHiTE, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and Improved Spool-Protector, of which the following is a specification.

My invention has for its purpose to provide a simple, inexpensive and easily applied device for use in connection with cotton or silk spools that serves to always keep the cotton or silk clean and from tangling.

Another object of my invention is to provide a device to be applied to spools of cotton or silk in the nature of a new article composed of elastic, soft rubber or any woven fabric colored according to the cotton or silk it protects, that can be readily slipped over the full spool and which, when thus applied, works equally well with a full or partially emptied spool and when the spool upon which it is applied is emptied, it can be conveniently removed and used on other spools of like color.

My invention is a protecting device for spools that embodies the peculiar features of construction hereinafter fully explained, specifically pointed out in the appended claims and illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a spool with my protecting device applied, the spool being shown as operatively mounted on the spool spindle of a sewing machine.

Fig. 2 is a perspective view of the spool and the protector device, the latter being shown separated from the spool; the thread on the spool being shown as having been passed through the thread guide in the protector.

Fig. 3 is a similar view of the protector and the spool and illustrates the manner in which the protector is applied on to the spool, and

Fig. 4 is a longitudinal section of a partiallyfilled spool with the protector mounted thereon.

My spool protector is in the nature of an endless band of elastic, soft rubber or any woven material and is preferably woven in one piece.

In the manufacture of my protector device, it is to be made in different sizes and colors according to the sizes of the spools and the colors of the cotton or silk wound thereon and of such widths as to entirely incase the contents of the spool and to engage with the opposite end of the opposite beveled surfaces 20-20 of the spool ends.

I prefer to make the protecting band of woven elastic since when of such material, it works equally as well on a full or a partially emptied spool, retains its relatively rigid shape, see Fig. 4, by reason of the opposite ends thereof engaging the opposite beveled edges 20 of the spool ends, as before stated.

The protecting band 1 has an eyelet 10, located midway of its ends, that forms a guide for the thread and a smooth contacting surface over which the thread rides as it is drawn off the spool.

By reason of having the eyelet midway of the ends of the band, a uniform tension is at all times on the thread and sufficient to cause the spool to turn within the band and with just enough friction to at all times hold the band in the proper position for protecting the thread until the spool is emptied, it being understood that since the band is not fixedly attached to the spool, it can be instantly removed from an emptied spool and as quickly applied to another filled spool.

y device is exceedingly simple and its use on thread spools, when mounted on the spool spindle of a sewing machine, tends to effect a better and more uniform outfeed of the thread than is possible on spools without the protector, since the protector positively prevents undue slack or tangling of the thread as it passes from the spool to the first thread guide on the machine, see Fig. 1.

What I claim is:

1. In combination with a spool of thread; an elastic covering over the same having an eye through which the thread passes.

2. In combination with a spool of thread; an elastic covering overthe same having an eye through which the thread passes, said covering being designed to engage the spool with yielding pressure whereby the spool may be turned with relation to the covering when drawin out the thread.

3. In combination with a spool of thread; an elastic covering over the same having an eye through Which the thread passes, said thread comprising an endless band of such covering being of a Width so that its oppo- Width whereby it is adapted to rest With its site ends engage the beveled surfaces of the opposite ends on the opposite beveled edges 1 ends of the spool whereby to hold the covof a spool and having an eyelet for the pas- 5 ering from Working endwise off the spool. sage of the thread therethrough.

4. As a new article of manufacture, a contractile fabric covering for a spool of JANE WHITE.
